Which sign would indicate tachypnea in a toddler and may signal respiratory distress?

• A. 20 breaths/min
• B. 30 breaths/min
• C. 35 breaths/min
• D. 40 breaths/min

Answer: (C)

Tachypnea is a faster-than-normal breathing rate for the child’s age, and it signals respiratory distress when the body is working harder to get adequate oxygen. In a toddler, a respiratory rate in the mid-30s, especially when the child is at rest, is considered rapid for age and suggests the child is experiencing breathing difficulty.

Think of tachypnea as your flag that the lungs or airways are under stress—perhaps due to infection, inflammation, fever, or hypoxemia. It’s important to pair this with other signs of distress, such as nasal flaring, chest retractions, grunting, or pallor/bluish color, and to monitor oxygenation if possible.

When counting, try to observe the child quietly for a full minute to avoid counting bursts from crying or playing. A rate around the mid-30s fits the pattern of tachypnea in this context, making it the best indicator among the given options.
